To play queuemeleon, open up the game here (Desktop/iPad only! Doesn't work on phone screen size)

Now take a mobile phone (or any additional device with a browser)

On that device, open up the url queuemeleon.herokuapp.com/blue_button (It is better to use separate devices because the game needs to be the active window to run)

Press the big blue button and watch the chameleon change color!

If you have no one else to play as red and yellow, you can ask me to play, or control all 3 colors at http://queuemeleon.herokuapp.com/admin

I am proud of this game, it is satisfying leveraging sockets (socket.io on node.js) to change the state of an application from multiple devices and see the updates without reloading the page.
